.SH DESCRIPTION

RAUC is a lightweight update client that runs on an Embedded Linux device and
reliably controls the procedure of updating the device with a new firmware.

RAUC is also the tool on the host system that is used to create, inspect and
modify update artifacts for the device.

This manual page documents briefly the
.BR rauc
command line utility.

It was written for the Debian GNU/Linux distribution to satisfy the
packaging requirements. Thus it should only serve as a summary,
reading the comprehensive online manual (\fBhttps://rauc.readthedocs.io/\fR)
is recommended.

.SH OPTIONS

The following general options can be used with most commands, however

Convert an existing bundle to casync index bundle and store.

.RE
.PP
\fBinstall\fR \fIBUNDLE\fR

.RS 4
Install a bundle.

\fBOptions:\fR

.RS 4

.TP
\fB\-\-ignore\-compatible\fR
disable compatible check

.RE
.RE
.PP
\fBinfo\fR \fIBUNDLE\fR

.RS 4

.RE
.RE
.PP
\fBstatus\fR [\fISLOTNAME\fR | \fBmark-{good,bad,active}\fR [\fBbooted\fR|\fBother\fR|\fISLOTNAME\fR]]

.RS 4
Without further subcommand, it simply shows the system status or status of a specific slot.

The subcommands \fBmark-good\fR and \fBmark-bad\fR can be used to set the state of a slot
explicitly. These subcommands usually operate on the currently booted slot if not specified per
additional parameter.

The subcommand \fBmark-active\fR allows one to manually switch to a different slot. Here too,
the desired slot can be given per parameter, otherwise the currently booted one is used.

\fBOptions:\fR

.RS 4

.TP
\fB\-\-detailed\fR

.SH ENVIRONMENT

.TP
.B RAUC_PKCS11_MODULE
Library filename for PKCS#11 module (signing only)

.TP
.B RAUC_PKCS11_PIN
PIN to use for accessing PKCS#11 keys (signing only)

.SH FILES

.TP
.B /etc/rauc/system.conf

The system configuration file is the central configuration in RAUC that
abstracts the loosely coupled storage setup, partitioning and boot strategy of
your board to a coherent redundancy setup world view for RAUC.

RAUC expects its central configuration file \fB/etc/rauc/system.conf\fR to
describe the system it runs on in a way that all relevant information for
performing updates and making decisions are given.

Similar to other configuration files used by RAUC,
the system configuration uses a key-value syntax (similar to those known
from .ini files).
